From Landungsbrücken, you can make boat tours into the harbour, available from various companies and take around an hour. Big ships provide more comfort, but smaller ships also go through the Speicherstadt. Both are well worth the money. Inquire about English language tours.
Dedicated to Altona's, Hamburg's and northern Germany's cultural history.
Rathaus Altona
Built in 1898, when Altona was still a separate city. It's an impressive building with influences of Italian Renaissance.
Walk 136 steps to the roof of this building to get a wonderful view of the harbour. The six-storey glass and steel building has the shape of a parallelogram and is reminiscent of a ship bow.
This used to be the city park of the independent town of Altona. Unlike Hamburger Stadtpark, this park has been left in a more natural state. On the northern edge of the park is Volksparkstadion, the home stadium of the football team HSV, as well as the multi-purpose Barclaycard Arena.
St. Pauli Piers
The most touristy part of Hamburg's harbour, close to the metro station with the same name. Piers connected with several bridges swim on the water adapting to the tide. There tourist boats land and you will find souvenir shops, restaurants, and snack bars. The sailing ship Rickmer Rickmers can be visited. The old passenger docks, from which (among many others) many of the emigrants to the Americas from eastern Europe left in the 19th century. Today they are a tourist hotspot, as the departure point for harbour tours and many public transport ferries. The stroll eastwards along the water from the S-Bahn station "Landungsbrücken" all the way to the HafenCity is very pleasant.
One of the biggest non-nuclear Soviet submarines, moored near to the Fischmarkt. Guided tours are possible.
